Under greenhouse planting conditions, the yield of tomato per mu is about 6000- 10000 kg, which is related to planting techniques and tomato varieties. Wool powder 802, the weight of a single fruit is about 200g, and the yield per mu is about 4000-5000kg. Yukang No.4 single fruit weighs about 175-200g, and the yield per mu is about 4500kg. Ruby, single fruit weight 75- 120g, yield about 3000-3500kg per mu.
1. Yield of tomato in greenhouse 1 mu
1, tomato yield per mu in greenhouse
Under greenhouse planting conditions, the yield of tomato per mu is about 6000- 10000 kg, which depends on planting techniques, tomato varieties, soil water and fertilizer conditions and other factors.
2. Yield of different tomato varieties
(1) wool powder 802 is suitable for greenhouse planting in spring and autumn and open planting in spring. The weight of single fruit is about 200g, and the yield per mu is about 4000-5000kg.
(2) Yukang No.4, the single fruit weight is about 175-200g, the single fruit weight is about 2750g, and the yield per mu is about 4500kg.

2. From seedling stage to flowering stage, the required nutrients account for 12% of the total nutrients. From the initial flowering stage to the complete flowering and fruiting stage, the required nutrients account for 25% of the total nutrients. From full flowering stage to harvest stage, the required nutrients account for 63% of the total nutrients.
3. The ratio of N, P and K required from sowing to flowering stage is 1: 1: 1. The ratio of nitrogen, phosphorus and potassium required from flowering to fruit setting is 1: 0.5: 1.5. The ratio of N, P and K required from fruit setting to fruit ripening is 1: 0.3: 2. The ratio of N, P and K required from fruit ripening to picking stage is also 1: 0.3: 2.
